c# find keywords in a string and remove it

c# remove word from string
c# remove character from string at index
remove character from string c#
c replace character in string at position
string.replace c#
c# remove characters from end of string
c# trim string to length
c# remove first character from string

Using string.Replace is the simplest approach:

foreach (var word in lists)
{
   sentence = sentence.Replace(word,"").Trim();
}

Although that will find the word in the middle of the string too. If you wanted to remove it only at the start you could use IndexOf check it's 0 and then take the string starting from word.Length using Substring. Or use StartsWith:

foreach (var word in lists)
{
   if (sentence.StartsWith(word))
   {
       sentence = sentence.Substring(word.Length).Trim();
     // break; // if only one
   }
}

C# how to remove a word from a string - MSDN, I have a whole big file in the string. I need to remove the words out one at a time. So add a loop around it. You will have to iterate over your find/  We can use String.IndexOf () to find the position of the substring and can use the starting index and number of characters to remove. The following example removes everything before and after substring ‘founder’ in a string. // Remove everything after founder. int pos = founder.IndexOf ("founder"); if (pos >= 0) {.


There are 2 options for you.

  1. First of all the Remove usage is incorrect. You just want to remove the keyword. If u pass 1 argument to remove it will remove from that index till end. Pass the length of keyword as second arg to Remove.

    s.Remove(index, len);

  2. If string contains it than replace the occurrence of keyword with empty string

    s.Replace("keyword", "");

Trimming and Removing Characters from Strings in .NET, Trim; TrimEnd; TrimStart; Remove; Replace; See also. If you are parsing a sentence into individual words, you might end up with words that have String class to remove any number of spaces or other characters from a The following example removes white-space characters, periods, and asterisks. C# remove (C# Reference) 07/20/2015; 2 minutes to read +2; In this article. The remove contextual keyword is used to define a custom event accessor that is invoked when client code unsubscribes from your event. If you supply a custom remove accessor, you must also supply an add accessor. Example


Another option is you could create an extension since you already know what items to remove.

using System.Text.RegularExpressions;

public static string RemoveFromList(this string sentence)
{
    new List<string>{ "ask-", 
                     "que-", 
                     "(app)", 
                     "(exe)", 
                     "(foo)" }.ForEach(name => 
                                       {
                                           sentence = Regex.Replace(sentence.Replace(name, string.Empty), " {2,}", " ");
                                       });          
    return sentence;
}

Useage

 var str = "ask- This is (app) a que- sentence.".RemoveFromList();

Note

I used Regex.Replace as it's possible you may have some blank spaces floating around after you remove the bad string/s, this helps ensure that doesn't happen.

[Solved] Remove string from match word c#, string test="Remove string from match word."; // first we get the index of from int index = test.indexof("from"); test = test.substring(0,index). foreach (var word in lists) { sentence = sentence.Replace(word,"").Trim(); } Although that will find the word in the middle of the string too. If you wanted to remove it only at the start you could use IndexOf check it's 0 and then take the string starting from word.Length using Substring.


C# Replace String Examples, We remove some characters and add new ones. With Replace we search for (​and exchange) one pattern for another. Here: We replace all strings starting with the word "bird" and ending with a digit char and a non-word char (like a space). The String.Contains, String.StartsWith, and String.EndsWith methods search a string for specific text. The following example shows each of these methods and a variation that uses a case-insensitive search: string factMessage = "Extension methods have all the capabilities of regular static methods."; // Write the string and include the quotation


Delete consecutive same words in a sequence, Given a sequence of n strings, the task is to check if any two similar words come together then they destroy each other then print the number of words left in the  Trimming and Removing Characters from Strings in .NET. 03/30/2017; 5 minutes to read +8; In this article.
